| Abstract: | The catalytic performance of a variety of metallic oxide catalysts for the alcoholysis of urea with 1,2-propylene glycol(PG) for the synthesis of propylene carbonate(PC) in monolithic stirrer reactor(MSR) and mechanically agitated slurry reactor(MASR) was investigated.The results have shown that ZnO-Cr2O3 is best in catalytic performance and that the yield of PC with a monolithic stirrer reactor is lower than that with a mechanically agitated slurry reactor.Optimum reaction conditions were identified,i.e.re... |
